Generate GS1 Data Matrix symbols that scan.
Dedicated GS1 Data Matrix profile with FNC1/application-identifier semantics. Configure GS1 Data Matrix below — Use GS1 AI syntax. BWIPP owns FNC1/separator encoding. Every symbol is decoded again on your device before export.
2D code generator
Type text, get a symbol.
Runs locally in your browser. Nothing is uploaded; the field clears after ten idle minutes.
Advanced (error correction, shape, GS1)
This symbology has no tunable options — the engine picks the densest valid symbol.
Style (colors, frame, caption, export size)
GS1 Data Matrix stays black on white until this output path has an independent color/raster qualification.
Outer frame
Frame and caption ship in the SVG download; PNG exports the bare symbol.

Usage
GS1 Data Matrix marks small parts and documents with dense square symbols: etch or print it where Data Matrix-style readers expect machine-readable serials.
- GS1 Data Matrix on electronic components for traceability
- GS1 Data Matrix on ID cards and tickets for gate scanning
- GS1 Data Matrix proofs exported as PNG at explicit module sizes
Shape
Pros
- GS1 Data Matrix scans on modern phone and industrial imagers.
- Every symbol is read back locally before preview or download.
- SVG export stays sharp for print; PNG covers quick sharing.
- Only the controls this symbology accepts are shown.
Cons
- GS1 Data Matrix needs calm quiet zones — nearby text breaks detection.
- Glare, blur and low contrast are the usual reasons a symbol will not read.
- Screenshots prove scannability, not print quality grading.
- Custom colors stay locked until contrast and tinted re-decode pass.
Form requirements
- Enter (01)09501101530003(17)271231(10)LOT123.
- Use GS1 AI syntax. BWIPP owns FNC1/separator encoding.
- Downloads stay locked until the local read-back reproduces the payload.

How it works
Three steps, all on your device.
The same engine that reads 2D codes writes them — every symbol is decoded again before you see it.
Tune and style
Only the controls this symbology accepts are shown; every symbol is read back to prove it scans.
Download and print
Take a resolution-independent SVG or a PNG at your chosen module size. Nothing is uploaded.
Questions
GS1 Data Matrix Generator & Specs, answered.
If you manage servers by hand, see the engineering services behind this tools series.
What can I encode in GS1 Data Matrix?
Use GS1 AI syntax. BWIPP owns FNC1/separator encoding. Example input is prefilled when the page loads.
How does GS1 Data Matrix stay scannable?
Error correction fixed by the symbology or QR-studio owned. Keep the quiet zone calm, use black-on-white for print, and export SVG for anything that gets resized.
Is my data uploaded anywhere?
No. Encoding and verification run entirely in your browser — the page makes no network requests with your data, stores nothing, and wipes the field after ten idle minutes.
